if you have just the one rifle, you dont need anything fancy. A good Hoppes 9 kit from Walmart will get the job done. If you want something that will last forever, a one piece stainless rod from Pro-shot, some 2" patches and the correct jags and you will be set.
So for the new rifle, give it a good cleaning before you sight in. This will get rid of all the protectant and any debris that collected from the shipping box.
Shoot enough to get on paper (which will also foul the barrel enough to start sighting in. You do not want to sight in cold bore after a cleaning, as the barrel still has lubricant and protectant. This may cause larger groups initially and you dont want to be "chasing your zero"; after around 3-5 shots you can start sighting in. If you are sighting right before a hunt, get it where you want it, then do not clean it, nor tweak the scope, nor tighten anything. Messing with action screws, scope rings, or cleaning can effect your cold bore zero.
If you want to check your cold bore shot, wait until another day and then put 3 down range. If you are happy, then pack it up ready for the hunt. I am not gonna get into the whole 3 vs 5 vs 10 round accuracy bullshit, as the Tikka is accurate and it only holds 3 in the mag. If a shooter can not hit a deer in three shots, then the deer won that round.
Have fun and be safe.
